Post insulators in substations are used to support and insulate electrical conductors and equipment, ensuring safe operation under high voltage conditions. They provide mechanical strength and electrical insulation, preventing the risk of short circuits and maintaining the integrity of the electrical system. Additionally, they help to minimize electrical losses and protect equipment from environmental factors, enhancing overall reliability and safety in power distribution.
Soil moisture typically enhances the effect of substation grounding by making the soil more electrically conductive. Soil moisture dissolves minerals, creating an electrolyte, or conductive medium. Substation grounding systems often employ the use of a grounding well, which is a casing that is driven into the aquifer, for this reason.
A substation is not a load but is a place where switching and voltage-level changing takes place. Accordingly, you cannot apply a 'power factor' to a substation.
Primary substation - when the transformer is HV/MV or MV/MV. e.g. substation designed for 132kV/33kV or 230kV/22kV or 33kV/11kV etc stepped down for MV distribution (mainly for utilities and heacy industries) Secondary substation - when the transformer is HV/LV or MV/LV. e.g. substation designed for 11kV/400V or 6.6kV/400V etc stepped down for LV distribution (mainly for residential, commercial) sometime referred to as a kiosk substation.

A substation that is smaller than the average substation. A substation converts electric power from one voltage to another.
That wire could use a better insulator.
The Substation which comes power from the power plant know as pooling substation.

Jefferson Substation was created in 1909.
Neuhof Substation was created in 1985.
Concourse Yard Substation was created in 1933.
In my line of work that is an Electrical High Voltage substation that is brand new. It is being built from a green field into an energized fully functional substation yard. There is no existing substation or remodeling of an existing one being done.
Birds use their feathers as an insulator by fluffing their feathers in winter to trap a layer of air in and around.
No. Electricity will flow right through it! So don’t use it as an insulator!
